# Marine units:
If your looking to use OZtopo on a marine unit and haven't yet purchased a unit make sure you buy one with a SD card slot.

If your unit uses a Garmin Propriety Card, yes OZtopo (and other maps) will work on these units. However the area that you can use/view will be limited by the size of the Garmin card you can use with each model. You need to check but most have only allow a maximum of 256MB (some 128MB some 512MB) which equates to about 1/3 of one state. Garmin cards are also expensive , eg US$100+ for 256MB card. In addition you will need a Garmin USB card writer at about US$100 to load maps onto these types of cards. These card writers only work on Windows 32 bit machines up to Windows Vista.

If your model is not listed please call or email
